Naughty naughty!!! :grin:
Great stuff- very invasive. SO..... Should everyone or most folks technically "steer clear"? Ya. Could there be a situation where you had a OCD landowner who planted one row with them, then slower stuff in following row.... Once the slower stuff got to height- the OCD landowner could spend every last second for years making sure they were eradicated.
They are invasive BUT they are a heck of a plant. My hometown in MI had 12' tall OO shrubs covering 200 acre game area- oh my gosh is that place off the hook amazing for cover, thickness, etc.
Really, lets bottom line this..... thick, awesome cover, resilient and FAST GROWING are the traits you are after. There's 10-20 other options I can think of that would offer you ALL the same benefits EXCEPT they would not be quite as fast growing. So- bottom line, really all you would be after is maybe a 5 year jump start on getting to your goals. Downside is invasive, etc. See what I mean?
